Abstract (en)
[origin: US6912263B2] At least one injector condenser ( 20 ) is used to supply secondary feedwater to the steam generator ( 1 ) during a phase in the course of which the temperature and the pressure of the coolant of the reactor coolant system ( 2 ) of the nuclear reactor are varied between hot shutdown conditions of the nuclear reactor and conditions making it possible to bring into service the residual heat cooling system (RRA). The injector condenser ( 20 ) is fed with steam withdrawn from an upper part of the steam generator ( 1 ), at a first inlet, and with feedwater from a storage tank ( 10 ), at a second inlet. High-temperature pressurized feedwater is supplied to the steam generator ( 1 ) by means of one injector condenser ( 20 ) outlet. The steam generator ( 1 ) is fed without using an additional pump for withdrawing feedwater from the storage tank ( 10 ) and for injecting feedwater into the secondary part ( 3 ) of the steam generator ( 1 ).
